Three ways to reduce the noisy office productivity tax
Deep work needs deep quiet
I was on a bank of desks, in an open-plan office, with a colleague opposite me. A steady stream of people came to chat with her. To each, she complained that it was impossible to concentrate in the office and often had to stay late to complete work. I thought it somewhat ironic that she prevented me and others from working, due to the very thing she was complaining about.
Open-plan office hell
Open‑plan offices have been found to reduce productivity and impair memory. They’re associated with high staff turnover. They make people sick, hostile, unmotivated and insecure. - Susan Cain
The open-plan office was meant to revolutionise work, breaking down barriers, fostering collaboration and saving property costs. Instead, it has created environments riddled with noise and distractions. Chief among these is human speech: colleagues chatting, phone calls and impromptu meetings.
Noise doesn’t affect everyone equally. Its impact varies dramatically between introverts and extroverts. Most managers are extroverts. Their preferences often shape workplaces that privilege one way of working while undermining another. This has consequences for productivity, stress, motivation and retention.
Speech is very distracting
Of all office noises, intelligible speech is the most disruptive to performance. - Julian Treasure
Our brains are wired to process language. Unlike the hum of air conditioning or the clatter of keyboards, speech carries meaning. Even when we try to tune it out, our minds involuntarily track nearby conversations. This “irrelevant speech effect” reduces focus and memory, especially for tasks requiring deep concentration like writing, coding and problem-solving. Studies show open-plan workers face more interruptions and take longer to resume tasks after distractions.
Introverts vs extroverts
Introverts are like a rechargeable battery. They need to stop expending energy and rest in order to recharge. This is what a less stimulating environment provides for introverts. - Marti Laney
Introverts and extroverts don’t just differ socially; they process stimulation differently.
Introverts run on quiet. Busy, noisy environments don’t just distract them, they drain them. For an introvert, calm isn’t a nice-to-have; it’s fuel. Constant interruptions and background chatter sap their energy and make deep focus almost impossible. In workplaces built for nonstop interaction, introverts often feel like they’re swimming upstream.
Extroverts are wired differently. They feed off buzz and energy. A lively space, full of chatter and movement, lights them up and keeps their creativity flowing. Silence feels suffocating; they need the hum of people around them to stay engaged. The very noise that exhausts introverts charges extroverts’ batteries.
Most managers are extroverts
We associate leadership with extroversion and charisma so instinctively that when we see someone who is quiet and mild-mannered, we tend to write them off. - Susan Cain
Extroverts dominate management roles. Their confidence in groups, verbal fluency, and networking ease often propel them up the ladder. As a result, workplaces are unconsciously designed for extroverts: open layouts, frequent team huddles and hot-desking reflect a belief that visibility equals productivity.
Productivity and stress
When we are interrupted, it takes an average of 23 minutes and 15 seconds to get back to the task. - Gloria Mark
Noise slows work and raises stress. Prolonged exposure to chatter elevates cortisol levels, fuelling anxiety and fatigue. Introverts, with their heightened sensitivity to stimuli, are especially affected. The result? Introverts may stay silent in meetings, overwhelmed by overstimulation. Deep-focus tasks take longer and are prone to errors. Extroverts, oblivious to these struggles, assume everyone else is equally comfortable.
Ways to reduce the productivity tax
Remote work is a form of autonomy and autonomy is the foundation of motivation. - Daniel H. Pink
So what’s the solution? Here are my suggestions:
Manager awareness: Train managers to recognise their own biases and understand that not everyone thrives in high-energy, open environments.
Flexible working: Allow employees to work remotely or in private spaces when tasks require intense focus. Empower them to work in the most effective way, taking account of role type and personal circumstances.
Zoning for different activities: Create quiet zones for deep work, collaborative zones for team interaction and social spaces for casual chats. Add plants and soft furnishings.
The result will be a happier, more engaged and productive workforce. A balanced culture values both spontaneous collaboration and solitary reflection, recognising that innovation often emerges in silence.

Jason Fried, 37 Signals CEO, said, “The office is the last place I’d go if I really wanted to get something done. Too many interruptions, too little control.” Many feel the same way.
Have fun.
Phil…
Completely true.
We have now evolved to have the remote version of office noise. It's called Slack :)
But at least we can decide how often to check it. ;)
